Unmanned aerial vehicles (UAV) shipped with on-board sensors have become an effective remote sensing (RS) tool in agriculture. They have been used mainly for image surveying and there are still many helpful aerial RS application to develop. Working with UAV it’s an added valuable point for any professional who wishes to succeed in this competitive market. Herein, you will have the opportunity to work in a novel and ambitious project with UAV applied to the emerging field of Precision agriculture (PA).
Estimating when it’s the appropriate time for harvesting, it’s one the most critical decisions for a farmer. A wrong estimation can lead to increased production losses. Currently, this task is done on the site mostly through visual contact with the crop: Looking to the fruits colour, smell, taste, and firmness. Although, this might work for domestic producer, it’s hard to accomplish for producers with many acres. A hypothesis for improving this agricultural management practice is to estimate the right time for harvesting by measuring the gases released by the fruits. So, the aim of this topic is to design an aerial-based approach for measuring the ethylene over a crop and analyse it feasibility for fruit maturity estimation.
The aim of this project is to study the potential of UAV for fruit maturity estimation. This will be achieved within the main steps: 1) Review of the state-of-the arte in gas sensors (electronic noses) and ripe estimation practices; 2) Design a sensor system based in open-source software and low-cost electronic boards; and 3) Field test in an apple plot with the designed system.
